Li-Ning JB4 "Dark Knight" — Stephen Curry PE

The Li-Ning Jimmy Butler JB4 "Dark Knight / Stephen Curry PE" is a landmark release in sneaker history. This stealth-black, armored silhouette was the very first non-Under Armour shoe Stephen Curry wore in an official NBA game during his sneaker free-agency run — a defining moment in the modern sneaker era. The retail version replaces Jimmy Butler's standard tongue symbols with Curry's official silver signature logo, marking the formal integration of his new Li-Ning partnership into the brand's flagship signature lines.

Scheduled for a highly exclusive, limited drop September 9–14, 2026 during Curry's promotional tour across China.

⚙️ Core Performance Technologies

  • Full-Length Carbon Fiber Chassis — An aggressive, curved carbon fiber flight plate is molded seamlessly into the base. It eliminates midfoot twisting, reduces arch strain, and acts as a rigid propulsion lever for explosive first-step acceleration.
  • Supercritical Nitrogen Midsole — Full-length nitrogen-infused Boom foam delivers a lower center of gravity with ultra-responsive bounce, tuned for quick-twitch lateral changes and hard landing protection.
  • Low-Slung Speed Upper — An ultra-low ankle collar shaves weight and drops your center of gravity while maximizing vertical ankle flex for crossovers, pull-ups, and step-backs.
  • High-Density HC Loc Outsole — Specialized honeycomb rubber tracks deliver massive multi-directional bite on indoor hardwood floors.

📏 Fit & Sizing — Braces vs. Bare Feet

  • Curry Setup (Rigid Braces) — If you wear heavy rigid ankle braces (Zamst A2-DX, thick orthopedic insoles, etc.), go half to a full size up. The low-volume entry and highly structured synthetic upper have zero stretch tolerance for extra hardware.
  • Standard Fit (No Braces) — Go true to size. The shoe wraps tightly around the midfoot like a glove to prevent internal heel slippage during hard lateral braking.
